FKAB I16 McAsphalt

11 700 m3 Bitumen & Oil Product Tanker

The FKAB design is a bitumen, chemical and product oil tanker, tier III, twin skeg with
independent cargo tanks for bitumen and asphalt with a temperature of up to 200°C.
The vessel is designed with single bottom and double sides for ballast water.
The high temperature variations require special design considerations, mainly because of
thermal expansion of tanks and pipes. The cargo tanks consist of two blocks, forward and aft of
the cargo room, with six tanks respectively in each block.The cargo tank support are arranged
in such a way that it allows free expansion in all direction. There is no structure inside the cargo
tanks.
Twin skeg powered by two (2) medium speed four stroke dual fuel (diesel / LNG) engines
coupled to controllable pitch propeller and two shaft generators connected via gear boxes,
shaft generators will also be used as motors (PTI) when running on slow speed with just one
main engine. Shaft generators will be connected to the electric net via a DC-link and frequency
converters allowing variabble speed of the engine /propeller for both PTI and PTO.
In order to save fuel the shaft generator is connected via a frequency converter allowing
optimum propeller rpm at various speed.
The vessel is designed for a service speed of 11,0 knots at 80% MCR with 15% sea margin,
with clean hull, at a draught and even keel with an output from the shaft generator of 250 kW.
Fuel consumption of main engine in LNG mode at 11.0 knots at design draught excluding shaft
generator and excluding sea margin under ISO standard ambient conditions and LCV 48,000
kJ/kg to be about: 9,3 ton per day
Fuel consumption of main engine in MGO mode at 11,0 knots at design draught excluding shaft
generator and excluding sea margin under ISO standard ambient conditions and LCV 42,700
kJ/kg to be about: 10.3 ton per day
